Microsoft Office RT may lack macros, add-ins, other features

Well, the good news, as you already know, is that Office RT will be preloaded on all Windows 8 RT tablets -- at least in preview form. The bad news, even if you spring for the full version, you may be dealing with a limited product. Word on the street is, that in order optimize performance and battery life, Microsoft pulled a number of features from the ARM-friendly version of its productivity suite. Among the missing features is support for macros, third-party add-ins and VBA scripts. A small number of other features are also reportedly on the chopping block, but without a final product to put our fingers on, it's not clear which ones are getting axed.
